Machining
Lathe CNC Parts
CNC milling represents a machining process that seamlessly
integrates computer numerical
control machining systems with multi-point cutting tools, often in
the form of milling cutters.
As a pivotal branch of CNC machining, CNC milling entails securing
the workpiece onto a machine
bed and methodically removing material from a solid block.
This meticulous process results in the fabrication of diverse
products, encompassing materials
such as glass, metal, plastic, wood, and specialized materials.
Product Details
CNC milling machines excel at cutting a wide range of materials,
including aluminum, bronze,
copper, ceramics, plywood, various steel types, stone, wood, zinc,
and numerous engineering
materials.
This versatility makes them perfect for crafting prototypes during
product development.
With CNC milling, you can easily fine-tune and make precise
adjustments until you achieve
the desired final product, offering accuracy and efficiency
throughout the manufacturing process.

CNC Machining Tolerances
Tolerances are not standardized across all processes and materials.
The final tolerances on your part depend on various factors, such as part size, design
complexity,
the number and size of features, materials used, surface finish,
and the manufacturing process
employed.
Once your order is confirmed, we conduct a Design for Manufacturing
review to identify areas that
may need modification for better manufacturability.
It's helpful if you can specify which areas in your design have
critical tolerances that must be met
and which can be adjusted, if necessary, to optimize production
time and cost.
| CNC Milling Tolerances |
| Limits for nominal size | Plastics | Metals |
| 0.5mm* to 3mm | ±0.1mm | ±0.05mm |
| Over 3mm to 6mm | ±0.1mm | ±0.05mm |
| Over 6mm to 30mm | ±0.2mm | ±0.10mm |
| Over 30mm to 120mm | ±0.3mm | ±0.15mm |
| Over 120mm to 400mm | ±0.5mm | ±0.20mm |
| Over 400mm to 1000mm | ±0.8mm | ±0.30mm |
| Over 1000mm to 2000mm | ±1.2mm | ±0.50mm |
| Over 2000mm to 4000mm | ±2.0mm | |
*Please clearly indicate tolerances for nominal sizes, below 0.5mm on your technical drawing. |

Advantages of CNC Machining Process
CNC machining offers several advantages compared to other machining
and manufacturing
processes:
1. Enhanced Precision and Accuracy:
CNC machines can consistently replicate components with precise
dimensions, ensuring each
piece matches the previous one. Computerized controls enable a
higher level of precision than
manual machining methods.
2. Quicker Turnaround:
CNC machining can significantly reduce production time. Unlike
traditional machining, where manual
machine setup is required for each operation, CNC machines can make
adjustments through simple
changes in the computer code.
These machines can operate continuously for longer periods, leading
to faster order fulfillment.
3. Scalability:
CNC machining is suitable for both prototyping and large-scale
production.
With minimal machine and tool preparation, thanks to CAD files,
prototypes can be rapidly and
accurately produced. Once a part design is approved, it can
transition seamlessly to full-scale
production.
4. Versatility:
CNC machining accommodates a wide range of designs in various
materials, including metals and
polymers. This versatility makes it ideal for manufacturing a
diverse array of parts and products.
